35-minute cell phone exposures at maximum power showed no immediate blood pressure or heart rate changes in healthy adults.

Plain English Summary

Summary written for general audiences

Finnish researchers exposed 32 healthy adults to cell phone radiation at both 900 MHz and 1800 MHz frequencies for 35 minutes each, then carefully measured their blood pressure and heart rate during and after exposure. They found no significant changes in either cardiovascular measure compared to fake (sham) exposure sessions. This study directly contradicted an earlier report that suggested cell phone use might raise blood pressure.

Study Details

A recent study raised concern about increase of resting blood pressure after a 35 min exposure to the radiofrequency (RF) field emitted by a 900 MHz cellular phone. In this randomized, double blind, placebo controlled crossover trial, 32 healthy subjects were submitted to 900 MHz (2 W), 1800 MHz (1 W) cellular phone exposure, and to sham exposure in separate sessions.

Arterial blood pressure (arm cuff method) and heart rate were measured during and after the 35 min R...

Arterial blood pressure and heart rate did not change significantly during or after the 35 min RF ex...

The results of this study indicate that exposure to a cellular phone, using 900 MHz or 1800 MHz with maximal allowed antenna powers, does not acutely change arterial blood pressure and heart rate.
